What is HIP 21958
In the modest Caelum, the celestial engraver's chisel, a K-type orange star shines about 642 light years away. Its light departed around 1384, while Europe was emerging painfully from the Black Death and the Christian kingdoms of the Iberian peninsula were accumulating centuries of Reconquista. Cooler than the Sun and bathed in an amber tone, it embodies the silence of stars that have begun to leave youth behind. The constellation, one of the smallest in the sky, was sketched by Lacaille in the eighteenth century as a tool for celestial workshops.
Where it is and when to see it
HIP 21958 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
